We conduct experiments to compare the performance of several variants of our method for ablation studies. The qualitative results are shown in Table REF . Full model represents the proposed Ms-CapsNet. CapsNet denotes the traditional capsule network [1]} without AFC module and multiscale operator. Besides, we implement our model without AFC module (w/o AFC ) and without multiscale operator (w/o multiscale). It can be observed that both multiscale operator and the AFC module can boost the change detection performance. The PCC values improve 0.14, 0.23, and 0.08 by the multiscale operator on three datasets, respectively. This is because the multiscale operator is beneficial to enrich the feature representations. In addition, the PCC values improve 0.36, 0.46, and 0.46 by the AFC module on three datasets, respectively. It is evident that local features can be effectively converted for primary capsules.
